실험 절차

To a stirred solution of 4-fluoro-3-phenoxybenzyl alcohol (0.22 g, 0.99 mmol) and triethylamine (0.14 g, 1.38 mmol) in ether (about 15 ml), under nitrogen, is added by syringe a solution of the acid chloride of N-(2-chloro-4-trifluoromethylphenyl) valine (1.5 mmol) in ether. The mixture is stirred for 30 minutes and then quenched with saturated aqueous sodium bicarbonate. The ether phase is washed with aqueous sodium bicarbonate, water and brine and filtered through silica. Evaporation of solvent, followed by thin layer chromatography using a circular chromatograph, eluting with 20% ether/hexane, gives the 4-fluoro-3-phenoxybenzyl ester of N-(2-chloro-4-trifluoromethylphenyl) valine, [4-fluoro-3-phenoxybenzyl 2-(2-chloro-4-trifluoromethylphenylamino)-3-methylbutanoate].
